London, July 16 : Rapid immigration has damaged community relations in parts of England and is the single biggest cause of public concern, an influential group of MPs have warned.
They are so worried that they told the British Government that it must act urgently to defuse tensions before the concern boils over into riots.
The MPs' devastating report concluded that migration has had a significant impact on communities and local services - greater even than crime and terrorism, the Daily Express reported.
The group condemned Labour Party's promise of a transitional fund to support under-pressure authorities as a "drop in the ocean".
It also revealed that tensions were rising between some settled ethnic communities and new arrivals because of increased competition for "race equality" resources.
The MPs stressed: "The Government needs to take immediate action to address public concerns about migration and to defuse tensions before they lead to disturbances."
The report by the Communities and Local Government Committee is the latest in a growing list of damaging studies warning that Labour's open-door immigration policy has piled pressure on our towns and cities.
Sir Andrew Green, chairman of Migrationwatch UK, said: "The Government still does not get it."
"It is not a question of managing local impacts, it is a question of a massive impact on our whole society from having to build the equivalent of seven Birminghams in the next 25 years," he added.
The Shadow Minister for Community Cohesion, Baroness Warsi, said: "This report is yet another indictment of the problems caused both by the Government's failure to control the numbers of migrants coming into this country and by its inability to know where migrants are living and to fund local authorities accordingly."
